This code is for low voltage. If the battery has gone dead and you had to jump start it or install a new battery you will need to clear the code and be okay. Otherwise is the battery going dead regularly?
Bad wire to regulator check wires bye moving them around one wire at a time if not then replace batery termanals or if battery is to old it will not take a charge
Well the charge light means the alternator is not charging the battery. You would need to get the alternator and circuits tested on the car. It could be a bad connection somewhere or other wiring problem.
SOUND LIKE ALTERNATOR NOT CHARGING BATTERY.CHECK BATTERY VOLTAGE SHOULD BE 12.6 VOLTS.MAY SURE BATTERY CABLES CLEAN AND TIGHT.WITH ENGINE RUNNING CHECK ALTERNATOR OUT PUT AT BATTERY.SHOULD BE 13.5 - 14.5 VOLTS WITH ENGINE RUNNING.IF ALTERNATOR FUSE GOOD AND ALTERNATOR BATTERY FEED WIRE AND VOLTAGE REGULATOR WIRES OKAY NOT DAMAGED.DRIVE BELT NOT SLIPPING OR BELT TENSIONER NOT DAMAGED.ALTERNATOR MORE LIKELY FAULTY.TURN OFF RADIO FIRST.BEFORE REMOVING NEGATIVE BATTERY CABLE TO KEEP FROM LOSING RADIO CODE.
the voltage regulator is built into the alternator,have you check the alternator connector for damage or corrosion check with a test light for voltage at the red wire that plugs into the alternator that is in the 2 wire plug connector as well as check the large red wire for voltage as this wire is the feed wire from the battery.you don`t say if this is a new or used alternator.if you have a voltmeter that is the best way to check for the proper amount of voltage at the test sites.the battery must have a minimum of 12.6 volts to start with higher is better.to test the voltage regulator need the engine running and you need a voltmeter to tell properly if it is working.at the back of the alternator their is a hole that looks like the letter D this is where you use something like a cotterpin and insert it into the hole you should feel a tab,push lightly on the tab and ground the cotterpin to the side of the alternator using the voltmeter you should see the voltage start to rise and hear it start to charge.the battery voltage and the feed wire at the alternator as well as the smaller red wire at the plug connector should be the same.charging voltage should be about 14.5 volts.
first you need to check your unit maybe it is grounded,,how to know if your unit is grounded? using tester get your tester in x1 mode, test the tip of battery terminal positive to positive negative to negative, automatically the tester make a deflection.after that switch it .. positive battery terminal to negative wich is the color black wire of the tester,if theres a deflection again ,,,, your unit is grounded
check the wiring from the alternator to the battery there is a fusible link located in the wire to prevent the battery from being overcharged. if the fusible link has blown it will not charge the battery
check for battery voltage at the charge post on the alternator and at the 2 wire connect with the key on .if you have it then its a bad alternator. if you have a belt spinning the alternator.
